Onduline Roofing Nottingham — Professional Installation for Garages, Sheds & Outbuildings

Onduline Classic vs Onduline Mini Profile — Which One Is Right for You?

Not every Onduline sheet is the same, and fitting the wrong product is one of the most common reasons an Onduline roof underperforms. Here is a straightforward breakdown:

Onduline Classic

• 3mm thick, 38mm corrugation depth
• 2m x 0.95m sheets
• Best for: garages, stables, workshops, larger agricultural outbuildings
• Carries the 15-year weatherproofing warranty when correctly installed
• The product most used by professional installers across Nottinghamshire

Onduline Mini Profile

• Shallower 24mm corrugation depth
• Best for: garden sheds, summerhouses, playhouses, and smaller structures
• Neater finish suited to domestic garden buildings

There is also a cheaper, lighter product sold at some builders' merchants under similar names. It looks almost identical but is thinner, less rigid, and less durable. We only ever supply and fit genuine Onduline Classic or Mini Profile from approved UK distributors — so you get the product that performs and the warranty that covers it.

If you are unsure which product suits your building, we will tell you at survey stage — not after the sheets are already on.

How We Install Onduline Roofing in Nottingham

We follow the manufacturer's installation specification on every job. No shortcuts. No improvised fixings. No guesswork.

Our installation process covers:

• Full structural check of the timber frame before any sheets go on
• Purlin centres set at a maximum of 61cm for pitches above 15 degrees
• Minimum 30 branded Onduline fixings per sheet — colour-matched nails with rubber-capped washers
• Side laps of at least one full corrugation
• End laps of 170mm minimum on steeper pitches; 300mm on shallower roofs
• Maximum eaves overhang of 70mm to prevent wind uplift
• Ridge pieces lapped by 125mm and correctly sealed at the apex
• All flashings and verge trims fitted and sealed to prevent water tracking

Using generic screws or non-branded nails voids the Onduline warranty entirely. The rubber-capped washers on branded fixings are what creates the watertight seal at every fixing point. We always use Onduline's own fixing system — not because it costs more, but because it is the only correct way to do the job.

Most single-garage Onduline re-roofs in Nottingham are completed in a single day. Larger structures or those requiring structural repairs will take longer — we give you a realistic timeframe before we start.

Replacing Asbestos Roofing with Onduline in Nottingham

This is one of the most important sections on this page — and one that almost no other Nottingham roofing contractor talks about openly.

Corrugated asbestos cement sheets were the standard roofing material for garages and outbuildings built before approximately 1990. Nottingham has a significant number of these structures, particularly across Aspley, Bulwell, St Ann's, Bestwood, and the wider post-war housing estates that ring the city.

The sheets look very similar to Onduline and other corrugated roofing products. Many homeowners assume a straightforward swap is possible. The legal position is clear: you cannot sheet over or work on top of asbestos-containing materials without proper assessment and licensed removal.

Under the Control of Asbestos Regulations 2012:

• Asbestos-containing materials must be assessed before any work begins
• Removal of bonded asbestos cement sheets must be carried out by appropriately trained operatives
• All asbestos waste must be correctly packaged, labelled, and disposed of at a licensed site

We manage the entire process for our customers. We arrange licensed asbestos assessment and removal before any Onduline installation begins. You do not need to find a separate contractor or manage two separate workstreams — we handle it as part of your roofing project.

If you have a pre-1990 garage or outbuilding in Nottingham and you suspect the roof contains asbestos, call us before touching anything. We will assess it and advise you correctly — at no charge.

Condensation and Ventilation — Getting It Right on Nottingham Roofs

One of the most frequent calls we receive is from Nottingham homeowners who have had Onduline fitted and are now seeing drips from the underside. In most cases, the roof is not leaking — it is condensation.

Onduline performs significantly better than steel on condensation because bitumen has better thermal mass than metal. However, if the building is heated, used as a workshop, or houses animals, warm moist air rises and condenses on any cold surface — including Onduline sheets.

Nottingham's East Midlands climate makes this a real seasonal issue. The temperature swing between day and night from November through to March is significant. A building that warms during the day and cools sharply overnight is a condensation risk without proper ventilation.

The solutions are usually straightforward:

• A ventilation gap of at least 25mm at eaves level on enclosed buildings
• An ONDUTISS AIR breathable membrane under the sheets on heated structures
• Avoiding sealed eaves that trap warm, moist air below the roof line

We advise on ventilation requirements at survey stage for every enclosed building — whether you are having a new Onduline roof fitted or troubleshooting an existing one. In most cases, condensation problems can be resolved without a full re-roof.

Planning Permission for Onduline Roofing in Nottingham

Most homeowners in Nottingham do not need planning permission to replace a garage or outbuilding roof with Onduline. Under permitted development rules, a like-for-like outbuilding roof replacement is generally allowed without an application.

However, there are exceptions — and Nottingham has several:

• Conservation areas — including The Park Estate, parts of the Lace Market, and areas of Mapperley Park. Material changes visible from the road may require approval.
• Article 4 Directions — Nottingham City Council has issued these in several areas, removing standard permitted development rights on outbuildings and minor external works.
• Listed buildings or curtilage properties — any outbuilding within the boundary of a listed property requires separate consent.
• Buildings visible from a public highway where the change of material constitutes a material change of appearance.

We flag any planning risk at the survey stage. We have worked across Nottingham and Nottinghamshire long enough to know which areas carry restrictions. If there is any doubt, we advise you to seek pre-application advice from Nottingham City Council's planning team before we start.

You will never arrive at the end of a job with us and discover you needed permission you did not have.

Frequently Asked Questions About Onduline Roofing

How long does Onduline roofing last?

Onduline Classic carries a 15-year waterproofing warranty when installed correctly using branded fixings. When well-maintained and properly fitted, Onduline can realistically last 20 to 30 years in UK conditions. The key factors are correct installation, sufficient fixings, and keeping the roof clear of debris, moss, and blocked gutters.

What is the minimum roof pitch for Onduline sheets?

The minimum pitch is 5 degrees (gradient 1 in 11) when laid on a full supporting deck such as OSB or plywood, or 10 degrees when fixed directly to purlins. At the minimum pitch, an end lap of 300mm is required. Most Nottingham garage roofs fall well within the workable pitch range.

Can Onduline roofing be installed over existing shed felt?

Yes — in many cases Onduline can be fitted directly over existing shed felt or boarding where the underlying structure is sound. We check this at survey stage. If the existing deck or purlins are rotten or structurally compromised, we address that first before any new sheets go on.

What is the difference between Onduline Classic and Coroline?

Onduline Classic is the premium product — 3mm thick, manufactured by Onduline Building Products, and carries a 15-year warranty. Coroline is a similar-looking but lighter-weight alternative from a different manufacturer. It is cheaper but less durable. We fit Onduline Classic because it is the product that performs at the level our 10-year guarantee requires.

Does Onduline roofing need planning permission in Nottingham?

In most cases, no. Like-for-like replacement of an outbuilding roof falls under permitted development. However, properties in Nottingham conservation areas, those subject to Article 4 Directions, or buildings visible from the road may need approval. We check this for you at survey stage — free of charge.

Is Onduline roofing noisy in heavy rain?

No — this is one of Onduline's genuine advantages over steel or polycarbonate. The bitumen material absorbs rain impact sound significantly better than metal sheeting. For stables, workshops, and garden rooms where noise matters, it is a real benefit.

Can Onduline be used to replace an asbestos roof?

Yes — but the asbestos must be properly removed first in line with UK regulations. You cannot sheet over or directly replace asbestos without an assessment and licensed disposal. We manage that process as part of our Onduline re-roofing service.

Does Onduline roofing cause condensation problems?

Onduline itself does not condensate the way steel does. However, heated or enclosed buildings with poor ventilation will experience condensation on any cold roof surface. The fix is usually eaves ventilation or a breathable underlay — not a new roof. We advise on this at the survey stage.

How many fixings does an Onduline roof need?

A minimum of 30 branded fixings per sheet is recommended for standard applications. Using non-branded nails or insufficient fixings voids the warranty and creates water ingress at every fixing point. We always use Onduline's own colour-matched fixings with rubber-capped washers.

What colours does Onduline roofing come in?

Onduline Classic is available in black, red, brown, and green. Black is the most widely stocked and typically the most cost-effective. The other colours are available to order and suit garden structures where aesthetics are a priority.
